Firefox will not exit completly, have to close it with Task Manager every time. Why?

It is as if something is still running within it wanting to connect, I have ran virus and spyware scans on my laptop and nothing has came up, but it behaves like spyware. I have seen that 15 others share a similar problem, I hope that Firefox will fix this issue in the next release.

Lightroom 4.2 Win 7 64-bit -have to kill process in Task Manager every time or can't launch

Lightroom 4.2 Win 7 64-bit -have to kill process in Task Manager every time or can't launch Lightroom. This seems like a bug? Any suggestions?

Does sound like a bug. Consider reporting to Adobe:
http://feedback.photoshop.com/photoshop_family/topics/new
In the mean time, I only have workarounds like start using a batch file.
Something is hanging it up upon exit, but I dont know what. Maybe a device or process/service? - did you try removing non-essentials? Check windows logs?

I switched on my PC and there was an update for realplayer. Since then firefox will not load. It is running according to Task Manager. I've downloaded a another copy of the programme using IE but whilst it loaded as a programme, does not open a window.

Hi again,
Helps if I give the correct link ! <br/>The press shift button appears to still work, but the option to start in safe mode from the programs listing of a standard install I do not think exists anymore.
Safe mode will start from a command line, (or a shortcut) and in some circumstances you may need to enter the full path name on a command or shortcut detailed instructions are at http://kb.mozillazine.org/Safe_mode
Remember (at least at this stage) do not make changes when you get the options list, just click on the continue button.
If you think that RealPlayer is causing the problem you could uninstall that for now.
Firefox recent versions are 3.6 4.0 (and 5.0 in beta). There is some debate as to whether creating new profiles or re-installing Firefox is the simplest method of troubleshooting and solving some of these problems, personally I use multiple profiles and multiple versions of Firefox, and tend to forget the required procedures are less than straightforward. For now at least try [[safe mode]] again.

Firefox will not save my Connections settings, so opens on manual proxy every time, rather than No Proxy?

I'm using Firefox 4.01 and it will not save my connections settings when I set them to "No Proxy" keeps defaulting to manual therefore it wont load any pages until I change it to "No Proxy" which I have to do every time I open firefox.

See:
* http://kb.mozillazine.org/Preferences_not_saved

Firefox will not open - I have reinstalled and used the profile manager solution. It was fine earlier today. IE working fine.

I tried the suggested solutions including the 'clean install', any help would be most appreciated. I've used the Profile Manager, which is not much use when the browser won't even open to test it. I've also reinstalled twice, installed updates and restarted numerous times.
Firefox does do this on occasion, but usually sorts itself out - not this time.
Help!

You should check for malware or go back into regular mode and see if temorarily disabling your antivirus helps.
You can try these free programs to scan for malware, which work with your existing antivirus software:

I started working for ChaCha, and now firefox will not work unless I manually close it in the process tree every time I want to use it. I also cannot open more than 1 page at a time.

I started working for ChaCha 11/26/2010, I had to download a program to take incoming questions.
Ever since then, Firefox will not work correctly, even if I am totally logged out of ChaCha, and the page is closed, if I try to open my browser using Firefox, it will not open, I have to go into the processor tree and manually end Firefox, then it will work, but it will only let me open 1 page at a time. For example I have Firefox open now, but if I go and click on the icon to open it in a new browser, it will not open, I either have to close this, or use IE-I HATE IE lol.
I cannot use the ChaCha add on you have because it is not for the new version of Firefox, please help, I love Firefox, but not being able to open more than one window/page at a time does not cut it, nor does having to manually stop it from processing. I have tried re-installing it too.
Thank you, Melinda

I should add that I face the same problem with Safari and Google Chrome.

After refomatting HDD, reinstalling Vista plus service packs, recovering files from Microsoft backup and installing new copy of Firefox 3.6, Firefox will not run. Have deleted all old M0zilla profile folders and reinstalled Firefox again to no avail.

After computer would not boot and could not be repaired, I reformatted the HDD, reinstalled Vista plus all service packs and updates, recovered files from Microsoft backup and installed new copy of Firefox 3.6. Firefox will not run.
I have deleted all old M0zilla profile folders and reinstalled Firefox again to no avail.
After intallation was completed, the automatic startup just placed a small box on the screen "Import wiz". This just sat there with no activity. After I closed this box, none of the Firefox start buttons would open the program -- just the blue rotating icon for about 2 seconds then nothing.

Hi,
Please try to rebuil the WMI repository.
For detailed information, please refer to the blog below,

If issue persists, due to sfc doesn't work, could you try to repair your system with the installation disk?
Best Regards.

Firefox will not update. Have uninstalled and re-downloaded. However firefox appears to not be able to connect for updats.

Firefox works well, except will not connect for updates

If there are problems with updating or with the permissions then best is to download the full version and trash the currently installed version to do a clean install of the new version.
Download a new copy of the Firefox application and save the disk image file to the desktop
*Firefox 30.0: http://www.mozilla.org/en-US/firefox/all.html
*Trash the current Firefox application (open the Applications folder in the Finder and drag the Firefox application to the Trash) to do a clean (re)install
*Install the new version that you have downloaded
*https://support.mozilla.org/kb/Installing+Firefox+on+Mac
Your personal data is stored elsewhere in the Firefox profile folder, so you won't lose your bookmarks and other personal data when you uninstall and (re)install Firefox.

Firefox will not display on the screen even though with Process Explorer I see Firefox.exe active but no CPU usage

I use Firefox v10.0.2 as default browser on Dell XPS8300 e/w Intel Core i5 & Windows 7 Ultimate and Compaq Presario CQ57 e/w Intel Core i3 & Windows 7 Home. More frequently on the (about 90% of attempts) than the Dell (50% of attempts) Firefox will not display to the screen when I click on icon. When it happens I cannot display other programs. I specifically say display because I believe Firefox has started. To circumvent the problem I installed Process Explorer on both machines and start this program first then click on Firefox icon. When problem occurs I can see Firefox.exe process in Process list; some CPU consumed but, then, no CPU activity. If I click on Firefox icon again another process opens in Process list but with same response - some CPU consumed and then no CPU activity. If I have 2 processes running and kill the 1st process, the 2nd will display and everything from then on is normal. If I do not open a 2nd process but kill the 1st process then click on Firefox icon Firefox is displayed and everything from then on is normal. This problem has occurred since original installation on both new machines. I've updated video drivers in both machines.

Ok, let's see if we can fix this and get it working for you!
First, if you start Firefox in [[safe mode|safe mode]] (restart your computer first, then when you open Firefox, hold down the shift key) does it start up more reliably? This is usually caused by a faulty add-on. If it does help, then restart Firefox, go into the Firefox button, then add-ons, and disable your extensions one by one until you find the trouble maker.
Also, try updating to Firefox 11, it has several bug fixes that might make life easier here.
Just as a few basic troubleshooting steps to make sure we have all the bases covered,
Run all Windows Updates, install all needed service packs, etc.
Update all your plugins (Flash, Java, etc.): [http://www.mozilla.org/plugincheck/ http://www.mozilla.org/plugincheck/].
Download and Install MalwareBytes Anti-Malware, run a full Scan. [http://www.malwarebytes.org/ http://www.malwarebytes.org/]. This helps check that there are no viruses on your computer causing issues. you can uninstall this program after you clean off any infections.

You can install a portable Firefox (ESR) version to access websites that do not work with the current Firefox release.

Firefox will not start. Have error message "Failed (unknown reason)". Now I cannot get to the Internet

I was browsing and was asked if I wanted to update Firefox. I clicked yes. Thought it loaded, but now I cannot get to the internet at all. Now when I attempt to open Firefox and click on HELP, it gives me a Downloading Firefox 3.6.7 - but it will not connect.

Just once or twice

Firefox will not start, advising already running, but WIN 7 Task Mgr says nothing else running. This is big prioblem!!!

Can't get Firefox started. Instead advice given that it's already running and to close it down. BUT, Windows 7 Task manager advises that neither Firefox nor anything else is running. The only way I can remedy the problem is to restart computer, and I am getting a bit weary of this. I've had this problem before I recently updated Firefox.. I never have this problem with Explorer or AOL, both of which are and always concurrently running just fine.

This is not a cure but will make it easier if Firefox locks up.

As a novice emailer, I keep getting "Firefox prevented this page from automatically redirecting to another page" and I have to close and start over again EVERY TIME.

I don't use this computer's new gmail very often. Therefore, I had some 150 emails that I was trying to go thru & delete if possible. Many emails gave another site to go to complete my understanding of this email. But "Firefox prevented...." statement appears on the top w/ only a blank screen. I try to go back a page...nothing happens. I have to close all the tabs and get out of it completely. Then I have to click on Firefox icon...go to gmail...select the same email if there was more to read on it or just skip to the next new email. Very frustrating to a computer-illiterate. I don't understand any of the computer lingo (jave...etc); it took me 1 hour to figure out how to get to this space to type in this question. I have already failed 3 times in asking/typing in the question box. PLEASE try not to give me technical phrases.....left, right, top, works best for me.... mahalo, cecile

I don't know if this is still a problem but to stop it go to Firefox>Options>Options>Advanced>General Then third line down there is a box to remove the warnings. (These instructions are for Firefox4; I don't know how to access this from other versions.)
I'm also not sure whether this just removes the service of stopping redirection or whether it just removes the warning so beware.

Firefox will not launch, including in Safe Mode or the Profile Manager

Firefox on my other machine will not visibly launch. There is occasionally a message stating "you already have a Firefox session running, please close it before opening a new one" when I make a second attempt. I have tried to follow all the directions in any of the troubleshooting guides or in the forum posts on other sites, but I cannot even open the Profile Manager or open Firefox in safe mode. We have done a fresh install and that has not helped. Any additional assistance would be appreciated.

You can try to disable the Java Quick starter and the Java Console extension in the Control Panel > Java.
Control Panel > Java > Advanced tab > Miscellaneous >Java Quick Starter (disable)
You can also disable the Java plugin in Firefox: Tools > Add-ons > Plugins

If I bring up fire fox and not connected to internet I get and error when I shut it down and connect to the internet and bring firefox up it will not open unless I remove the prosses in task manager is this normal

when shuting down Firefox after not being connected to the internet the processes remains and I have to go into task manager and remove the process manually or I get a message that Firefox is already started and it will not come up

Sofar I have found (off internet),
A)that if you go into sleep mode, the wifi shuts down or powers down.
B)sleep mode must be disabled in order for wifi to continue.
C)you can check this by going into wifi and seeing the iphone every 20 seconds or so looking.
D)as far as handoff ,I still not to sure but I think BOOTH units must overlap each other in order to handoff from 1 to the other.
Show much bs on the web that I have to filter the pages and there not enough time in the day to go thru it all.

Firefox will not exit completly, have to close it with Task Manager every time. Why?
